I think I found a partial solution to this one. The overheating is caused by
the Nvidia driver. The driver is forcing video hardware acceleration all
the time and the GPU is working its nuts off continuously, even when it
is not doing much. There is no need for this at all. so, what to do to
alleviate this?
Right click on the desktop, select properties.
Select the settings tab /advanced button/ troubleshoot tab
Set hardware acceleration to None
Click on enable write combining
The laptop will run much cooler, probably by as much as 30 degrees
centigrade!
There are six settings for the hardware acceleration, try running it on
each and see which setting is the most stable for you. On the highest
setting I could expect a crash every other day.
The other issue which can have an adverse effect is the build up of
dust. Even a little seems to have quite a great effect. Clean the dust
from the fan and the ducts once a month. All you have to do is to
unscrew five little screws on the laptop bottom (on the panel with all
the grilles), remove the panel and use a small brush to remove any dust
from the panel underside and all around the fan.
My 7720g is now running at 39 degrees centigrade rather than 88 degrees
which used to be the norm.
